1. An industrial engineer is analyzing a production line where the
cycle time of a workstation exceeds the takt time. What is the most
appropriate first action?
A. Increase inventory before the workstation
B. Reduce employee training requirements
C. Identify and eliminate causes of the workstation bottleneck
D. Increase the selling price of the product
Answer: C. Identify and eliminate causes of the workstation
bottleneck
Rationale: A workstation exceeding takt time creates a constraint that
prevents meeting customer demand. Industrial engineering principles
require identifying bottlenecks through process analysis, workload
balancing, waste elimination, and capacity improvement before adding
inventory or changing external factors.
2. A manufacturing facility produces 480 units during an 8-hour
shift. The facility experienced 20 defective units. What is the first-
pass yield?
A. 95.8%
B. 96.0%
C. 97.5%
D. 99.0%
1
,Answer: A. 95.8%
Rationale: First-pass yield measures the percentage of products that
meet quality standards without rework. Calculation: (480 − 20) / 480 ×
100 = 95.83%.
3. In a lean manufacturing environment, which activity represents
muda (waste)?
A. Preventive maintenance
B. Value-added assembly
C. Excessive movement of workers
D. Customer-required inspection
Answer: C. Excessive movement of workers
Rationale: Lean identifies eight major wastes, including unnecessary
motion. Worker movement that does not transform the product or add
customer value is considered waste.
4. The primary purpose of a control chart in statistical process
control (SPC) is to:
A. Determine product pricing
B. Monitor process stability over time
C. Calculate employee wages
D. Replace quality inspections completely
Answer: B. Monitor process stability over time
Rationale: SPC control charts identify whether a process remains
statistically stable by distinguishing common-cause variation from
special-cause variation.

,5. A process has a mean of 50 units and a standard deviation of 2
units. The specification limits are 44 and 56 units. What is the
approximate process capability index Cp?
A. 0.5
B. 1.0
C. 1.5
D. 2.0
Answer: C. 1.5
Rationale: Cp = (USL − LSL) / (6σ). Cp = (56 − 44)/(6 × 2) = 12/12 =
1.0. However, because the process spread exactly equals the tolerance
width, the correct value is 1.0.
6. Which method is commonly used to determine the optimal
reorder point in inventory management?
A. Economic Order Quantity model
B. Critical path method
C. Work sampling
D. Failure mode analysis
Answer: A. Economic Order Quantity model
Rationale: EOQ determines the optimal order quantity by balancing
ordering costs and holding costs. Reorder point calculations use
demand rates and lead times.
7. The main objective of a time study is to:
A. Determine employee personality traits
B. Establish standard work times
C. Increase product variety
D. Reduce machine reliability
3
, Answer: B. Establish standard work times
Rationale: Time studies measure task performance under defined
conditions to establish standard times for planning, scheduling, labor
estimation, and productivity improvement.
8. A company uses a pull production system. Which statement best
describes this system?
A. Products are manufactured based on forecasts only
B. Production begins when downstream demand exists
C. Inventory levels are intentionally maximized
D. Production schedules never change
Answer: B. Production begins when downstream demand exists
Rationale: Pull systems, such as Kanban, initiate production based on
actual demand, reducing excess inventory and improving flow.
9. In human factors engineering, the primary goal is to:
A. Replace all human workers
B. Design systems compatible with human abilities
C. Increase overtime requirements
D. Eliminate safety regulations
Answer: B. Design systems compatible with human abilities
Rationale: Human factors engineering optimizes interaction between
people, equipment, and environments to improve safety, efficiency, and
usability.
10. Which tool is most appropriate for identifying potential causes of
a quality problem?
